(5-Bromofuran-2-yl)(2,3-dihydro-4h-benzo[b][1,4]thiazin-4-yl)methanone CAS 1089630-83-0

Description

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.

(5-Bromofuran-2-yl)(2,3-dihydro-4h-benzo[b][1,4]thiazin-4-yl)methanone (CAS 1089630-83-0), molecular formula C13H10BrNO2S and molecular weight 324.19 g/mol, is a CATO reference standard with documented purity and traceability.

(5-Bromofuran-2-yl)(2,3-dihydro-4h-benzo[b][1,4]thiazin-4-yl)methanone (C13H10BrNO2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, bromine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
